2 Claims.

The present invention relates to what is believed to be a novel'method and means of providing a dependable weather seal between abutting portions of frame members such as are used in the'construction of wooden door and window frames, and the primary purpose of the invention is to incorporate a plate-like shield in the structure at a point of vantage to provide a substantially water-tight jointlbetween the adjoining portions of the frame structure.

In reducing the principles of the inventive conception of actual practice, I found it expedient and practicable to utilize a right angularly shaped plate, this being employed as an insert and being fitted into saw kerfs or grooves formed in the abutting companion portions of the stile and stool, respectively, whereby to provide a simple, economical, and efficient assemblage aptly fitted for the purposes intended.

Other features and advantages will become more readily apparent from the following description and drawing.

In the drawing:

Figure 1 is a fragmentary sectional viewshow- 5 ing adjoined end portions of the stile and stool of the window frame with the improved sealing plate in position.

Figure 2 is a view of Figure 1 observing it in a direction from right to left.

Figure 3 is a fragmentary perspective view showing the stile and stool in the process of as sembly with the saw kerfs or grooves formed therein. 7

Figure 4 is an elevational detail View of' the safeguarding plate unit per se.

In the drawing the conventional wooden window frame is denoted by the numeral 5. I have shown one'vertical stile 6 and the adjoining complemental horizontal stool I. As iscustomary, one end of the stool I is fitted into a keyway 8 formed in the stile, as illustrated in Figure 3. Before the parts are assembled, relatively narrow saw kerfs 9and ID are formed at the points shown to provide slideways'for the shield or weatherproofing unit I i. This part H is slipped into place after the complete window frame has been assembled.

Naturally, the part ll may vary in proportion, and its constructional details may be slightly different from the arrangement depicted in Figure 4. Essentially, however, the part H comprises a substantially L-shaped plate resembling, in some respect, a light weight miniature angle iron. In the preferred embodiment of the invention the upstanding flange l2, which fits into the groove or kerf 9, has an outwardly bent feather edge knife formation, as indicated at I3. The lower horizontal fiangeid has a similar upturned knife edge i5, and these features are deflected laterally at the requisite angle to insure firm imbedding into the parts 6 and 1, as disclosed to advantage in Figure 1. Naturally, the so-called seal i i is of a length commensurate with the transverse dimensions or widths of the parts 6 and 1. Consequently, when it is in place, it bridges the existing or conventional vertical channel it, as disclosed in Figure 2. Normally, without the seal in place, water runs down the groove 15 and between the ends of the parts 6 and l, materially shortening the lives of such parts. Not only this, the water, when abnormal or excessive, is apt to be ruinous to the wall structure, wall paper, and so on.

It is to be observed that the cross-sectional shape of the part i is such that the vertical flange thereof abuts a portion of the so-called keyway 8, the free knife-like edge thereof projecting into the kerf 9 and being securely imbedded in the body of the part 6. The horizontal flange extending into the kerf l0 and being similarly imbedded enables said part H to effect a more secure joint between the parts 6 and. 1 than would otherwise be. Primarily, however, the interlocking feature is secondary to the weatherproofing feature, as is evident.

It is thought that the description taken in connection with the drawing will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

I claim:

1. In a structure of the class described, a vertical stile having a horizontal groove intersected by a vertical groove, a stool having one end fitting into said horizontal groove, said stile and 4 stool being provided with right angularly disposed saw kerfs extending completely across the transverse dimensions thereof, and an L-shaped metal plate interposed between the stile and stool and having its flange portions fitted into said kerfs in the manner and for the purposes described.

2. In a structural assemblage of the class described, a vertical stile having formed in one face thereof a horizontal groove, said groove extending transversely from one vertical edge to the opposite vertical edge, the upper wall of said groove being provided with a vertically disposed kerf running horizontally the complete length of the groove and opening through the opposite vertical edges of said stile, a horizontally disposed stool having one end fitting snugly into said groove, that end of the stool projecting into said groove being formed with a kerf complementary to said first-named kerf and extending horizontally at right angles to said first-named kerf and opening through opposite longitudinal edges of the stool, and an L-shaped metal plate interposed between the stile and stool and having one flange projecting into the first-named kerf, and the other flange projectin into the second-named kerf, said flanges having a driving fit in said kerfs and being of a length commensurate with said kerfs.
